Rhino 5 display point clouds?

I was wondering if there is a way to use a point cloud display mode in v5? Maxwell has its reference mxs files that display as point clouds through its plugin. Is there some sort of display plugin that can help with this to improve viewport speed?

Points can be grouped together into a cloud using the PointCloud command. Very large numbers of points typically display and process faster as a cloud instead of a selection of individual points

I frequently put point clouds which will be used for reference in a separate .3dm file, and then use Worksession to attach the files with the references to the file I’m working with.

David,

I actually wanted to show existing mesh as point cloud representation instead of the dynamic block display.
